The late Detlef Mertins distilled a lifetime of scholarship and research on Mies van der Rohe into this massive and authoritative survey of the master’s work and thought. Seven hundred drawings and photos illustrate the entire arc of a career that took Mies from Peter Behrens’ office in Berlin to a global practice in Chicago as the primary exponent of international modernism. “Less is more” and “God is in the details,” have become part of the everyday language of architecture. To some he was a god-like figure; others dismissed his buildings—even the best of them—as unlivable, dysfunctional, and authoritarian. It’s time for a reappraisal.
